This unit price calculator takes the figures you already have and applies the relationship behind unit price calculations for you, giving price per item, unit price and you save from cost, cost, number of items, number of items, volume, volume, weight, weight and type.
What Is the Unit Price Calculator?
The unit price calculator turns cost, cost, number of items, number of items, volume, volume, weight, weight and type into price per item, unit price and you save.
It is a quick way to get from the numbers you have to the number you need, without setting up a spreadsheet or reaching for a formula.
How the Unit Price Works
Each result follows from the ones before it, and the calculator shows every step, so a surprising answer can be traced back to the input that caused it.
Round your inputs to the precision you actually know, and keep more precision than that in the intermediate steps.
Getting a Result You Can Trust
Run the calculation twice with slightly different inputs. A sensible calculator moves its output in proportion; a wild change points to a unit or a decimal point problem in what you entered.
Write the inputs down next to the answer. It takes a moment and it is the difference between a number you can explain and one you cannot.
A Worked Example
Working through an example, with cost set to 10, cost set to 5, number of items set to 2, the calculator returns unit price of 2.5, and unit price (unit price 2) of 0, and unit price (unit price 3) of 0.5. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out price per item?
Enter cost, cost, number of items, number of items, volume, volume, weight, weight and type. The calculator then works through the relationship and reports price per item, unit price and you save.
What does the unit price actually calculate?
It takes cost, cost, number of items, number of items, volume, volume, weight, weight and type and converts them into price per item, unit price and you save using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter cost?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
